That's why I said classmates, since they can safely be assumed to be the
same age (or in a close range).

Also, you are assuming this person (or any of his acquaintances on
Facebook or WhatsApp) never once stated their age, which is unlikely.

But there are really countless of ways that this information can be
obtained given the amount of information Facebook usually has.

The most ridiculous way I can think of is using computer vision (or a
real person) to count the candles on a birthday cake in a picture.

In short, if they really want this information, they can get it pretty
easily.

Relatives and close friends are usually also on Facebook and they might
remember about the birthday even without FB telling them. They say
"Happy Birthday" and your date and month of birth is leaked; they might
say "Happy 22nd birthday!" and the year of birth is also leaked.

Let's hope so!
